2.5 Unlocking the SIM card
By setting a PIN (personal identification number) code of the SIM card, you can protect your
SIM card from illegal use. If this function is activated and the PIN protection code is set, you
have to input the PIN code to unlock the SIM card for regular use every time you power on
your phone.
Users can clear the code. In this condition, the SIM card cannot be protected from illegal
use.
A. Hold the End key to switch on the phone;
B. Input the PIN1 code, press “Clear” to erase the input errors and “Ok” to stop. For
example, to set the PIN1 as “1234”, input 1, 2, 3, and 4 in turn; then, press “Ok”.
If you enter an incorrect PIN code three times in a row, the network will lock your SIM card
and the phone will ask for PUK1 code.
Note:
Your network service provider will set a standard PIN code (4-8 digits) for your SIM card. Please
change it with your private password.
2.6 Unlocking the device
By setting a password for your phone, you can protect your device from illegal use. After
this function is selected, you have to input the password to unlock your phone for regular
use. Users can deactivate the phone lock code. In this case, your device may not be
protected from illegal use.
A. Hold the End key to switch on the phone;
B. Input the phone password. To clear any errors, press “Clear”, to end, press “Ok”.
For example, if the password is set as “1122”, enter 1, 1, 2, and 2 in turn and press “Ok”.
If you forget your phone’s password, please contact with the dealer or the authorized local
customer service center.
2.7 Connecting to the network
After the SIM card is unlocked, the mobile phone will automatically search for the network
and the screen displays a searching mark.
Once connected, the name of the network provider appears at the central top of the text
and image area. Now you are registered on the network.
Note:
The prompt of “SOS” (Emergency call available) shown on the screen indicates that your phone
is beyond the network service area or your card is not validated. However, you still can make an
emergency call according the signal strength.
